IRONING ROLL Filed June 13, 1928 INVENTOR lub ATTORNEY Patented Mar. 25,1930 iran stares GEORGE A. MUMFOB-D, OF ROCEESTER, NEW YORK IRONING ROLLApplication. filed .Tune 1 3,

The present invention relates to cushions such as used in padded rollsand beds of ironing and pressing machines and other places where similarconditions exist. An object of this invention is to provide aconstruction in which the cushion has greater durability and will notmat. Another object of the invention is to provide a cushion which is soconstructed as to provide a large space for the collection of vapor.Another object of the invention is to provide a cushioned surfaceVformed of a plurality of rigid surface forming elements so mounted thatno lateral strains are imposed upon the resilient means H which supportsthem. A still further object of the invention is to provide a cushionedsurface formed of a plurality of surface forming` elements which arereadily removable to permit the repair of the cushion.

To these and other ends, the invention consists of certain parts andcombinations of parts, all of which will be hereinafter described, thenovel features being pointed out in the appended claims.

In the drawings:

Fig. l is a transverse section through a padded roll of an ironingmachine embodying the present invention;

Fig. 2 is a sectional view through a frag- 39 mentary portion of theroll on the line 2 2,

F ig. 3 is an enlarged sectional view through one of the guides and oneof the surface forming elements; and

Fig. A is a view showing one of the elements partially in section andpartially in side view arranged in one of the channels or guides, theresilient means also being shown in partial section and partialelevation.

In the illustrated embodiment of the invention, 1 illustrates a shafthaving collars 2 thereon supporting a hollow cylinder 3 forming thesupport as a whole for'the cushion. The cushion, in this instance, isformed by a plurality of surface-forming members 4 in the form of rigidplates provided with perferations 5 through which the vapor or steam maypass after passing through the covering pa d 6. so as to keep the pad ina dry condition.

The members 4, in this instance, are ar- 1928. Serial No. 285,151.

ranged in parallel lines and guided against lateral movement on thesupporting cylinder 3. To this end, the supporting cylinder is providedwith a plurality of longitudinally extending guides. Each of theseguides are of channel formation having a bottom wall i conforming to thecylinder 3 and secured by welding to the latter. From this bottom wallproject two side walls 8 which have at their outer edges inwardly turnedHanges 9 60 forming a restricted outlet for the channel and also actingas stops. Each channel has al plurality ofsurface forming members tguide ed therein, and arranged end to end. To this end. a web ll isprojected from the rear face of each elongated surface forming member 42ane is guided by the walls of the restrictedy ortlet 10 of the channel.At the free end of ths web two outwardly extending flanges l2 areprovided which cooperate with the side walls 8 and the flanges 9. Thiscooperationl between the iianges l2 and the side walls andi, alsobetween the web l1 and the ends of the. iianges 9 prevents any sidewisemovement of the surface forming member et while permitting the latter tobe depressed. The flanges 9 limit the outward movement of the surfacefer-ming members.

Resilient means is interposed between the surface forming members andthe support for said members. In this instance, this resilient meanscomprises a plurality of leaf springs 13 superimposed one upon the otherand loclred together by clips 14 having side arms 14a fitting in notches20 in the sides of 85 the springs. These leaf springs form an archedspring means and the top of each arch abuts the bottom 7 of the channelor guide while the ends of the arch abut the flanges l2. To confine eachset of springs to one surface forming member each of said surfaceforming members have projecting from it two stop lugs l5 adjacentopposite ends of each member and serving to conline a set of springsbetween them.

Removable heads 16 close the ends of the drum or cylinder 3 and extendbeyond said cylinder substantially to the periphery of the roll as awhole. One of these heads is provided with ports 17 opening laterallybe- 100 1G apparatus connected to the roll, little or no moisturecollects upon the springs and, in this way, the life of the springs isextended.r

It is apparent that a button or other hard device passing between thepadded roll and an ironing surface will cause one of the sur# faceforming members to be pressed inwardly against a set of springs 13. Ofcourse, the surfacev forming member will roel; in the channeled guide,depending on' which side of gmthe center of the member is engaged by theharddevice, and will return to its initial position after passing out ofengagement with such device. Each surface forming member is removable oris held against lateral shiftgsging so that no stra-inis imposed uponthe springs or resilient devices which hold the surface forming membersin normal positions. The devices may be readily removed from thechannels by removing them longi- :Le-tudinally of the channels, causingthe springs to travel withthem. A ylarge space is pirovided in which thevapor may collect andthe springs are so mounted that only a small amountof the jvapor can reach them.

- It will be noted that longitudinally extending channels are providedfrom one endV oftheroll to the other and the vapor passing into andthrough these channels tends to maintain thecush'ioned surface in aheated -iaconditionand thus in a dry condition. Art

the same time the resilient or spring means which opposes the movementof the surface forming members is housed against the action of thevapor.`

s What I claim as my invention and desire to secure by Letters Patentis:

l. An ironing surface comprising a rotary support, a pluralityof surfaceforming meinbers, resilient means acting upon said sur-A face formingmembers to hold them in normal positions, and guiding means between thero' tary support and the surface forming kmembers preventing sidewisemovement of the Y surface forming members in the direction of turning'ofthe rotary member.

2. An ironing surface comprising a rotary support, o-f'a plurality ofsurface forming members each having a rigid web projected vfrom theinner side thereof and extending C? longitudinally of the axis ofrotation .of the support, resilient means acting on said surface formingmembersto hold them in nor'- inal positions and means cooperating withopposite sides of said webs to guide the surface forming members on thesupport toward parallel relation to each other and tothe axes ofrotation of the support, a plurality of surface forming members guidedin each of said channels and held against sidewise movement in thedirection of turning of the rotary support, and resilient means arrangedin the channels for holding the surface forming members in a normalposition.

Yt. An ironing surface comprising a support, a plurality 'of surface'forming members providedwithopenings and movably mounted on thesupport, resilient means opposing the' movement ofthe lmembers on thesupport, and means housing the resilient iieaiis and providing spacesthrough which vapor may be drawn from the openings in the surfacefo-rming members without contacting with the resilient means.

5. An ironing surface. comprising a plur f rality of surface formingVmembers formed with perforations and karranged in Vparallel rows,resilient means opposing the movement of said members, and meansenclosing said resilient means and providing parallel channels throughwhich vapor passing through the surface forming members may be drawnwithout contacting with the resilient means. k6. The combination with achannel member having a restricted outlet, of a surface forming memberhaving a web projected from the inner side thereof and guided by thewalls of the restricted outlet of the channel, means carried by said webfor limiting the outward movement of the surface forming member, twoabut-ments carried by the web within the channel, and bowed spring meanshaving its end portions cooperating with the abutments and its bowedVportion cooperating with the bottom of the channel member. l

7. An ironing surface comprising a rotary support, a plurality ofparallelfchannel members arranged longitudinally of said support toprovide vapor spaces between them, a plurality of surface formingmembers guided in each channel, and resilient means opposing themovement of the surface formingk members and arranged in said channels.
